How Electoral College Representation Has Changed Over Time

Source: Washington Post
Author: Denise Lu


Best Practices:
  • Nice use of a timeline and a tile map
  • Using two distinct colors
  • Using colors that have nothing to do with political parties
  • Good annotations
  • Show the outliers really well
  • Labeling each State
  • Great "how to read" chart at the top
  • Very easy to understand
  • State comparisons are easy
  • Context included both in time and by State
Recommended Enhancements:
  • Needs a title
  • Include the latest over- or underrepresentation next to the State label
  • Include the source
